To gain automatic entry into someone's computer without logging in, you would have to add yourself (Your computer\username) to their administrative group. You can do this to your daughter's machine by accessing 'Computer management' through Control Panel->Administrative tools. Once that is done, you can easily do the \\ComputerName\C$ and gain complete access, because windows is recognizing that your computer\username is a member of their administrative group... so it gives you access. You can then map to this drive freely, so that a drive letter is associated with it. There are several ways to gain entry into a computer... this is one of them. You can map single directories, and such, but you said you wanted complete access... this is the easiest way... Unless you wanted to remote into their machines with Remote Desktop Connection. Found in All Programs->Accessories->Communication.
